Solution

Superconducting material kept inamagnetic field expels the magnetic flux out its body

when cooled below the critical temperature and exhibit perfect diamagnetism.This is called MEISSNER EFFECT. 

It is found that as the temperature of the specimen is lowered toTc,the magnetic flux
is suddenly and completely expelled from it.The flux expulsion continues for
T<Tc.The effect is reversible.

  • When the temperature is raised from below Tc.The fluxdensity penetrates the
    specimen again at T=Tc and the material turns to the normal state.
Concept: Meissner Effect
